Abstract: 696,538. X-ray apparatus. PICKER X-RAY CORPORATION WAITE MANUFACTURING DIVISION, Inc. May 29, 1952 [Nov. 15, 1951], No. 13693/52. Class 98 (i). The apparatus comprises a demountable X - ray table having a portion constituting a box-like member and another portion constituting a panellike member, the various parts of the table being adapted to be disassembled and stored within the box-like member, and to be enclosed therein by the panel-like member, whereby the table may be packed into a unitary chest-like structure. The box-like member may also support a mast carrying an adjustable support for an X- ray tube, a shutter and a fluorescent screen, the mast and the parts mounted thereon being disassembled when required and packed in the box-like member. The X-ray tube, the control equipment, and accessories may be packed in a separate chest. The apparatus is readily transported and set up, and may be used for radiography or for fluoroscopy in horizontal and vertical positions. The apparatus is shown assembled for horizontal fluoroscopy in Fig. 1. The table has end frames 30, 31 hinged to a front panel 8, and held apart by a rail 36 fitting in slots therein. The end frames are fixed to a box 5 by bolts 35 (see also Fig. 8). The table top 40 has grooves 160 engaging rollers on brackets 42 on the end frame 31. The end 41 of the top has a shoe 162 riding on rail 36, and a member 168 engaging a rail 37 on the top edge of panel 8. Thus top 40 may slide on its support longitudinally, locking means being provided, and when member 168 reaches a gap in rail 37, the top may pivot about the rollers on brackets 42 into a vertical position in which it is latched for vertical fluoroscopy. For radiography, a carriage 38 for a Bucky grid and a photographic film placed to run along rails 36, 37. The box 5 has a frame 20 running on longitudinal rails, and a sub-carriage 22 movable at right-angles on frame 20. A mast, comprising two parts 23, 24, hinged together and latched at 26, is rotatably mounted on sub-carriage 22. A carriage 45 is slidable on the mast and counter-balanced by a spring within the mast, and carries a pivoted arm 46, in turn carrying supports for an X-ray tube 52, a shutter 56, and a fluorescent screen 48. To pack the apparatus for transport, frame 20 and sub-carriage 22 are moved to one corner of box 5 as shown in Fig. 8, and fastened in position. The shutter 56 and screen 48 and their supports are removed from arm 46, and placed in holders which are provided for the various parts on the bottom of box 5. The X-ray tube is removed for separate packing, and arm 46 is removed and packed in the box. Carriage 45 is run up to the top of the mast, which is then folded and stowed in the box, and carriage 38 is stowed above the other parts. The table is unfastened from the box, rail 36 removed and clipped under the top 40, which is removed and placed over the parts already fastened in the box. End frames 30, 31 are folded back against front panel 8 which is fastened as a lid to close box 5 and secured by hasps 9. A chest 65, Fig. 36, has compartments for the remaining apparatus. A control box 66 is packed in a compartment 67. This control box, when in use, is connected to the X- ray tube by cables 61, and to a timer 70 by another cable. Cables 61 are packed in a compartment 62, and timer 70, a foot switch 72, spare parts box 79, gloves 76, goggles 77, and an apron 78 are packed in adjacent compartments. The X-ray tube 52 is placed in a holder 74 which is placed in a compartment 73 and which carries springs 75 to prevent damage when the lid is closed. A collapsable stand 68 for the control box 66 may be mounted in the lid 69 of the chest. Alternatively chest 65, when empty, may be stood on end to form a stand for the control box.
